They are some good points Mike. We have to remember the whole reason the hoon laws are here today is for people taking risks in the first place in HPV (or any vehicle for that matter) with possibility of injury.
I am keen to get involved with Barbs etc, and i think its vital to do a drivers course no matter how old you are/experienced or amazing you think you are (though people that think they are amazing are the same ones that are ruining it for us real enthusiasts) and its a small price to pay to be able to have your "time and place" however crowded it may be.
It seems the trend with younger people such as myself is that they NEED to take risks and prioritise having their back end out around a corner to enjoy themselves, and giving them opportunities/facilities such as barbs etc is a great privilege but we need more community awareness of cost and where to start. Its almost programmed into teenage minds to test the limits.
I certainly wish i had the opportunity to race around when i was younger.
